Most Suitable Method for Prototypes of Deep Drawings and Diverse-types-and-small-quantity production.

Features

Achieve the great shortening in process, because of the original drawing that is added the slit at the stage of material. It is possible to make the deep container product in ONE SHOT, because the slit that optimized to materials, thickness, and draw ability. So it can make various drawings. Moreover we produce the deep drawing that exceeds the limiting drawing ratio of material. And then, we offer the parts of 3D curved surface shape that cannot be produced by ordinary drawing, and also achieve low initial cost and shortening of start-up span for new productions.

Advantages of One-Shot Deep Drawing

Reduce cost: 1/3 -1/5 price.
The lead-time for dies is greatly shorter.
It is the most suitable method for covers and cases that need not airtight.

Disadvantage of One-Shot Deep Drawing

It is unsuitable for the product needs airtight.

An Example

Customer Requirements

• Some strength should be able to be secured.
• The cylinder shape by deep drawing. It needs the shape of rib and lance that have spring characteristics on the side.
• Airtight is not needed.

Proposal Method

• One-shot deep drawing enables to exceed the limiting drawing ratio of height.
• The number of dies or process will be reduced, because it is added the slit at the stage of materials.
• The side of parts will be processed before drawing and no more process like cam bending.

Advantages

• It is possible to greatly reduce in unit costs and initial costs, because of the reduction of process. The spring characteristic of the side is stronger by adding the slit.
• The necessary strength can be secured by drawing shape of bottom.
